Have you heard of Newton, Pascal, Maxwell, Leibniz, Pythagoras, Einstein, Aristotle, Curie, and Turing? Do you know what they did and a little about their lives?
They were likely all dead before you were born.
Do you know some things about the Manhattan Project, Bell Labs, Bletchley Park, the Apollo Project, the Gutenberg press, the invention of carbon steel?
I’ll go further. If I said ‘he was referencing Science, not science’ would that make any sense?
I was a CS professor for a long time. Like many of my STEM colleagues, I taught the history of the ideas in my discipline as an intrinsic and important part of the curriculum. It’s also good pedagogy, since the long process of getting closer to the truth or developing more powerful technology is part of the toolbox we are trying to impart.
The commenter's point is that History as an academic discipline organized by institutions is part of the humanities departments.
It's not a deeper point.
Of course science has its own history and that history is examined (sometimes) in the course of scientific education. That's not what's at issue.
What's at issue is that History as a subject and other Humanities disciplines are systematically devalued in STEM disciplines and by scientific cultural mouthpieces and participants in STEM endeavors.
